Angelo's Stand ability was brought forth by the mysterious bow and arrow, and apparently they're also connected to DIO. After defeating Angelo, Jotaro thought that the danger had left the city, and tries to find the whereabouts of the bow and arrow.

For all of those you killed, 
including my Gramps!
!لأجلِ كُل من قتَلْت، بمن فيهم جدِّي
Für alle, die du getötet hast,
auch für meinen Opa!
Por todos los que mataste,
¡incluido mi abuelo!
Por todos los que mataste,
¡incluido mi abuelo!
l’âme de mon grand-père
et de tous ceux que tu as assassinés !
Per tutti coloro che hai ucciso,
incluso mio nonno!
Arrependa-se de todas as vidas que tirou,
incluindo a do meu avô!
